Important objects of the vinvention are to provide a heating apparatus,of theV character described, which will function to 'radiate and diffusea high degree of heat on a relatively low fuel consumption, which issimple in its construction and arrangement,`

compact, safely operable, which embodies parts that are readilyaccessibleand remov` able, which is durable and eflicient in its use, Y

, v.and comparatively inexpensive to manufac- 'tureand economical tooperate.

tending around its entire perimeter. A rectangularly shaped casing 4,providing a hot air chamber and having an open lower end, is`

removably Vmounted on the bottom 1 and Vmaintained on the latter byits'engageinent PATENT. oFFiCE i with the bottomV flange 8. The casing 4is providedfwitliy a top cover 5, which ispreferably removable but maybe fixed in position if desired.

All of the walls theicasing 4, and the top cover 5 of thelatter,areformed with a plurality of perforations 6 for permitting the passageandenfianation of heat from within the casing 4. The front wall of thecasing 4 is further provided with a (hinged door 7,V

which is disposed adjacent to the lower end thereof to allow access'tothe interior of the. l

casing'll for anypurposes required.

A cylindrical base 8 having an open lower end, is removablyfmounted on`the center of tion byan annular rib 9 formed on the latter.

A cylindrical tapering firepotV 14, Vhaving fopen upper and lower ends,vis removably mounted on top of thebase 8. ,The base 8 is provided'withan annular rib 15, which engagesthe lowerend of thev lower lfirepot 14 for VmaintainingY the latter in position von the ,5

base '8. ,Y A flame spreader 16is removably mounted `in thefu'pperportion'of thefre pot 14 andv consists of a fiat, circular, lowerspreader kplate 17 and a similarlyl shaped upper spread- The flamespreader plates 17 and 18 are positioned horizontally and spaced fromeach other by a plurality of vertically disposed flanges 19, which areformed integral with the top of the lower spreader plate 17. The upperspreader plate 18 rests upon the top of the flanges 19, and thearangement of the latter forms a pair of air passages, respectivelyindicated at 20 and 21, between the upper and lower flame spreaderplates 17 and 18. The air passages 2O and 21 intercommunicably intersecteach other at the center of the. spreader plates 17 and 18, and extendat right angles relatively to each other. K i y The outer ends 22, ofthe flanges'19, project beyond the periphery of the lower spreader plate17, and seat in respective recesses 23, which are formed in the top edgemargin of the fire pot 14. The recesses 28 establish open ends for theair passages 2O and 21, thereby providing communication between thelatter and the interior of the casing 4. The engagement of the flangeends 22, in the recesses 23 supports and maintains the entire flamespreader 1G within the lire pot 14.

The spreader plates 17 and 18 are provided with similar, scalloped orserrated peripheral edge margins 24 providing passage openings for thefire flame therethrough. rlhe upper spreader plate 18 is furtherprovided with a centrally disposed opening 25, which is surrounded by avertically disposed, annular flange 26v formed integral with the top ofthe upper spreader plate 18.

A vertically disposed heating cylinder 27 is removably mounted on thetop of the fire pot 14 and fiame spreader 16. The heating cylinder 27consists of an outer shell 28 and an inner shell 29 forming an annularheating chamber 30 therebetween. The top of the heating chamber 80' isclosed by an annular cover 31 and the lower end thereof is open. Thelower end of the outer shell 28 seats upon the top of the fire pot 14and is maintained thereon by an annular flange 82 formed integral withthe upper end of the fire pot 14, the lower endof the inner shell 29 isengaged by the annular flange 26, of the upper spreader plate 18.

rlhe innerV shell 29 provides an air passage 83 having an open vupperend communicating with the interiory of the casin g 4. The lower end ofthe air passage 33 communicates with the flame spreader air passages 20and 21, through the opening 25 formed in the upper spreader plate 18.

A flue pipe 84, for providing proper draught action to promotecombustion, communicably oins the upper end of the heating chamber 30with some suitable flue stack structure.

Fuel gas is supplied by a suitable conduit 35 provided with the usualcontrol valve 36 and having its outlet mounted in the bottom of theburner housing 10 directly beneath the depending lower end of theconically shaped Vgas spreader 11. The proper air mixture is suppliedthrough separate air conduits 37, which communicate with the burnerhousing 10 below the conically shaped gas spreader 11. The air conduits37 are provided with a suitable regulating element 88 to establish theproper fuel admixture.

The fire pot 14 is provided with an opening 39, at the front thereof,which, in conjunction with t'he casing door 7, permits the convenientllighting of the fuel in the burner element,'and further permits viewingof the combustion when establishing its adjustment.

The fuel admiXture, in entering the burner housing 10, through the gasand air conduits 35 and 37, will be spread in passing through theconically shaped fuel spreader 11 and the two superposed burner plates12 and 13. vThe fire flame, through the draught action of the flue pipe34, will be drawn upwardly into the heatingy chamber 30 through thepassage openings in the edge margins of the two flame spreader plates 17and 18, whereby the hea*- ing cylinder 27 will be constantly maintainedat a very high temperature.

The constant circulation of the air through the air passages 20 and 21,of the fiame spreader 16, which latter is constantly subjected to anintense direct fire, and through the air` passage 30 in the innercylinder shell 29, will cause the heating of the air to a very highdegree of temperature to be continuously disseminated through themultiplicity of openings 6 in the casing 4 for heating the chamber inwhich my improved heating apparatus may be located.

The separated admixture of the gas and air to form the fuel and thearrangement of the fuel spreader 11 and burner plates 12 and 18, in themanner stated, provide important features. of the present invention inestablishing perfect combustion and a high degree of temperature on aminimum fuel consumption.

It is, of course, evident that changes in the contuor, form, proportionsand details of construction may be resorted to without departing fromthe spirit or sacrificing any advantages of the invention..

The present invention provides a most efhcient device of its kind.,which may be safely and economically operated for heating purposes in anindividual stove, as herein disclosed, or when embodied in a heatinginstallation of the usual hot air system.
